I have a SM-G9880 BRI (taiwan) version and using in Australia. I have all the 3G/4G options but I'm unable to select any 5G - even though the phone is a 5G phone. I know my carrier does not use 5G in my area at this time, so is it not showing any 5G options because 5G is unsupported? Is it SIM related or would it be because I have a BRI (taiwan) CSC? I know others in Australia with SM-G9880 TGY versions using 5G (on different carrier) and they have 5G options... Just confused whether the 5G options are disabled because of the SIM, or because of the CSC??? :confused:

If its CSC related, I might try Samkey to change the CSC to TGY...
HOW do you change CSC from BRI to TGY in ODIN if Frija downloads exactly the same file for both??

HOW do you change CSC from BRI to TGY in ODIN if Frija downloads exactly the same file for both??
to answer my own question here, again, since nobody ever seems to come back and post their solutions,

The TGY and BRI firmwares are in fact identical, but Odin flashing to the China CSC (CHC?) and back to BRI/TGY forces TGY/TGY/TGY/BRI on the phone (or maybe its because my sim card was inserted this time?) - this still didn't give me 5G connectivity because Taiwan probably added 5g long ago and the posts recommending the TGY change pre-dated 5G there. And since the process factory wiped me anyway i went ahead and installed TWRP for snapdragon, no issues.

Still no 5G on my SM-G9910 using AT&T, I'm calling those ferks back tomorrow.

Can't believe Taiwan didn't have 5g when this was written its one of the most tech advanced countries in the world lol why do you think China wants to take it back 😔

    @cheetah2k

    Is changing to hk firmware version using Samkey what you ended up doing? Was it easy.... I am not Tech savvy. I got this phone from eBay seller who was showing in Sydney but the phone ended up coming from Taiwan

    This is the method I used (creds to user jabreel.torrin in the S10 forums. I did modify this though to suit the S20U) - You don't need to Odin flash the TGY firmware as its identical to the BRI - only CSC needs to change from BRI to TGY :good:

    1. Buy 3 credits (can't buy 2) from this seller that on ebay that I used : https://www.ebay.com.au/itm/SamKey-Code-Reader-3-Credits-UNLOCK-Fast-Service/324110503100?ssPageName=STRK%3AMEBIDX%3AIT&_trksid=p2057872.m2749.l2648
    2. After buying the Samkey credits you will be emailed the username and password for the Samkey App (you need this!)
    3. Enable developer options on your phone: Settings > About phone > Software Information > Tap "build number" 8 times or until you see a pop-up message that says "Developer mode has been enabled".
    4. Turn on USB debugging on your phone: Settings > Developer options > USB debugging > Allow USB Debugging > Tap "OK"
    5. Go to www.samkey.org and download the Samsung USB drivers (if you havent installed any samsung software on the PC already) and the Samkey application
    6. Install the drivers first, and then install Samkey application on your computer > Connect your phone to your computer with a usb cable > Login with the username/password you received from the ebay seller.
    7. Click the "Read Info ADB" button to make sure your phone has been accepted by ADB
    8. Insert the CSC code you want into the "Change CSC (Buyer)" field > With the BRI SM-G9880 you want to insert TGY (where is shows PHN in the pic below)
    9. Click the "Change CSC" button > Confirm that you want to spend 1 or 2 credits (for me it was 1, but some report 2 used).
    Let the application do it's work after which it will reboot and then you're good to go. :fingers-crossed:

    For me it was seamless and worked so easy. Zero complaints. 5 min later I had a TGY phone - and I have reserve credits for the next Samsung phone I need to change Hope this helps guys!

    5G has not been activated on BRI csc as there is no 5G in Taiwan yet. Its best changing to TGY however you will only get 5G using sim tray 2 (meaning you will not be able to use SD card at the moment).
